Measurements of seismic waves over many years suggest the Earth's core is deformed and reshaped by conditions of extreme heat and pressure.

The heart of our planet has been spinning unusually slowly for the past 14 years, new research confirms. And if this mysterious trend continues, it could potentially lengthen Earth's days — though the ...

Add Yahoo as a preferred source to see more of our stories on Google. A wealth of new information about Earth’s inner core has surfaced in recent months. Scientists now have evidence that the planet’s ...

The surface of Earth's inner core may be shape-shifting, new research suggests. The study, published Feb. 10 in the journal Nature, looked at earthquake waves that have skimmed the edge of the inner ...

The iron-rich core at the center of our planet has been a crucial part of Earth's evolution. The core not only powers the magnetic field which shields our atmosphere and oceans from solar radiation, ...

A bullet-speed experiment reveals that the Earth's inner core may be softer and more dynamic than previously thought.

Earth's inner core is solid and blistering hot. For decades, scientists have known the inner core is solid thanks to the pioneering work of Danish seismologist Inge Lehmann, who first proposed its ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance. The surface ...

The rotation of Earth's inner core may have paused and it could even go into reverse, new research suggests. The Earth is formed of the crust, the mantle and the inner and outer cores. The solid inner ...

Earth’s core consists of a solid iron-nickel ball rotating within a layer of liquid metal. But that ball may not be as simple as it seems: new research suggests the inner core contains its own inner ...
